X-band SAR measurements to extract motion-related parameters of offshore wind farms

This study deals with the observation of off-shore wind turbines using X-band Synthetic Aperture Radar (SAR) measurements acquired by the Spanish PAZ satellite mission. Wind turbines are installed increasingly offshore in utility scale wind farms equipped with enough capacity to satisfy the demand for renewable energy. Especially in northern Europe, the number of large offshore wind farms is increasing rapidly. Hence, in this study, spectral information is extracted from X-band SAR measurements to monitor wind turbines belonging to the Robin Rigg off-shore wind farm in Scotland, UK. Experimental results demonstrate the ability of SAR measurements to provide information about motion parameters associated to the wind turbines.
